Chapter 2 — Configuring the CK31
52 CK31 Handheld Computer User’s Manual
The Wireless Printing applet is available in the Control Panel
and separates the task of wireless printing setup from other
Bluetooth management tasks.
The Wireless Printing applet uses the concept of a “current
wireless printer.” The CK31 connects to the current wireless
printer when your application opens the wireless printing COM
port on the CK31. If there is no current wireless printer selected
on your CK31, there is no wireless printing COM port
registered on your CK31. You must select a current wireless
printer on your CK31, as described in the next section,
“Selecting the Current Wireless Printer on the CK31.”
The Wireless Printing applet performs these tasks on the CK31:
• Helping you select the current wireless printer
• Storing the current wireless printer in the registry
• Registering/deregistering the wireless printing COM port
• Storing the wireless printing COM port in the registry as the
WPort
Specifically, the current wireless printer is registered and
deregistered on Bluetooth stack load/unload. If you select a
different current wireless printer, the existing wireless printing
COM port is deregistered and the new one is registered instead.
The Wireless Printing applet uses the Bluetooth COM Port
Control to handle COM port registration/deregistration.
Selecting the Current Wireless Printer on the CK31
By default, there is no current wireless printer selected on the
CK31.
There are three ways to select the current wireless printer:
• Discovering the printer using Bluetooth device discovery
• Manually entering the printer’s Bluetooth device address
• Choosing the printer from a list of previously discovered
printers
